Definitions
- the invention relates to a hybrid adapter for fiberglass plug connectors.
- Standard connectors are, for example, plug connectors of the type ST, FC or SC.
- Small form factor connectors are, for example, the types LX.5, LC or MU.
- adapter is in this case used when two different types in one group are intended to be connected to one another, whereas hybrid adapters connect plug connectors from different groups.
- U.S. Pat. No. 5,274,729 discloses an adapter for standard connectors by means of which the different types ST, FC and SC can be connected to one another.
- DE 101 41 449 A1 discloses a universal adapter for the group of small form factor connectors.
- the adapter is composed of two symmetrical housing halves which each define a receptacle for a plug connector.
- the housing halves are designed such that they are each suitable for receiving all of the three types LX.5, LC or MU.
- a sleeve In the interior of the housing halves is arranged a sleeve which receives the ferrules of the two plug connectors to be connected.
- LX.5 plug connectors have a ferrule which protrudes from the housing of the plug connector and is shorter than that for LC or MU plug connectors, with the result that the housing half is formed with a pin which, during an insertion procedure, moves a laser light flap away such that the ferrule is not damaged.
- DE 699 06 230 T2 discloses a hybrid adapter, by means of which it is possible to receive plug connectors from different groups.
- the hybrid adapter comprises an alignment sleeve for axially aligning ferrules, having a support element which defines an essentially central hole through said support element, the hole comprising a first section and a second section.
- the first and the second section are aligned in the longitudinal direction and are located close to one another, the inner surface of the hole tapering increasingly at a predetermined angle of less than approximately 5 degrees.
- the support element comprises a first inner wall which at least partially defines the first section, the first inner wall comprising a plurality of first contact points which are spaced apart from one another symmetrically over the first inner wall, the first contact points being dimensioned in order to receive a first ferrule of a first diameter which has no tapering.
- the support element comprises a second inner wall which at least partially defines the second section, the second inner wall comprising a plurality of second contact points which are spaced apart from one another symmetrically over the second inner wall, the second contact points being dimensioned in order to receive a second ferrule of a second diameter which is not the same as the first diameter and likewise has no tapering.
- the invention is therefore based on the technical problem of providing a universal hybrid adapter and a sleeve suitable therefore, by means of which it is also possible to connect LX.5 plug connectors to standard connectors.
- the sleeve is of stepped design.
- the transition from the first diameter to the second diameter takes place at a right-angle.
- the sleeve has an axially continuous slot.
- the right-angled transition ensures that it is possible for the ferrule having the smaller diameter to be inserted at least up to the transition, but preferably even as far as into the region of the larger diameter. Even in the case of short ferrules of LX.5 plug connectors, this ensures that the ferrules can be brought together edge to edge. Owing to the continuous slot, it is in this case possible for the sleeve to compensate for manufacturing tolerances of the sleeve itself and of the ferrules.
- the ferrules can be reliably brought together edge to edge, they may have both a UPC (Ultra Polishing Contact) ground surface and an APC (Angle Polishing Contact) ground surface.
- the former is a planar-parallel ground surface, and the latter is a ground surface at an angle of 8° or 9° in order to deflect reflections at the coupling point.
- the length of the section of the sleeve having the first smaller diameter is smaller than the length having the larger diameter. This increasingly ensures that the ferrule having the smaller diameter is inserted in the region of the sleeve having the larger diameter, with the result that better contact is made.
- the ratio is preferably at least 2:3, further preferably the ratio being selected to be in the region of 1:3.
- the sleeve is made of ceramic, bronze or plastic, ceramic being particularly preferred.
- the first housing part is formed with an integrated laser protection flap, whose preferably spring-loaded flap is automatically pushed against the housing wall without coming into contact with the ferrule when a plug connector is inserted.
- the first housing part is in the form of a universal adapter for small form factor connectors, reference being made as regards a preferred embodiment to DE 101 41 449 A1, express reference hereby being made to said disclosure.
- the second housing part has an opening for the purpose of receiving FC and ST plug connectors, it being possible for an FC or ST interface, which is preferably made of metal, to be inserted in said opening.
- the FC or ST interface is provided with a radial groove, into which a sprung, forked metal sheet can be plugged on from the front side of a front panel.
- the interface can be selected to be very short, and the adapter can be detached simply and rapidly from the front side.
- the second housing part has a separate sleeve receptacle for the purpose of receiving an SC plug connector, it being possible for said sleeve receptacle to be latched to the first and second housing parts.
- a front frame having an integrated laser protection flap is latched onto the second housing part.
- the second housing part for the SC plug connector is preferably fixed to a front panel by means of two lateral spring clips.

Abstract
Description
- This application is a continuation of application Ser. No. 11/251,009, filed Oct. 11, 2005, which application is incorporated herein by reference.
- The invention relates to a hybrid adapter for fiberglass plug connectors.
- Known fiberglass plug connectors can be split into two groups, namely standard connectors having a ferrule diameter of 2.5 mm and small form factor connectors having a ferrule diameter of 1.25 mm. In this case, there are different types in each group. Standard connectors are, for example, plug connectors of the type ST, FC or SC. Small form factor connectors are, for example, the types LX.5, LC or MU.
- The term adapter is in this case used when two different types in one group are intended to be connected to one another, whereas hybrid adapters connect plug connectors from different groups.
- U.S. Pat. No. 5,274,729 discloses an adapter for standard connectors by means of which the different types ST, FC and SC can be connected to one another.
- DE 101 41 449 A1 discloses a universal adapter for the group of small form factor connectors. In this case, an embodiment is disclosed in which the adapter is composed of two symmetrical housing halves which each define a receptacle for a plug connector. In this case, the housing halves are designed such that they are each suitable for receiving all of the three types LX.5, LC or MU. In the interior of the housing halves is arranged a sleeve which receives the ferrules of the two plug connectors to be connected. LX.5 plug connectors have a ferrule which protrudes from the housing of the plug connector and is shorter than that for LC or MU plug connectors, with the result that the housing half is formed with a pin which, during an insertion procedure, moves a laser light flap away such that the ferrule is not damaged. DE 699 06 230 T2 discloses a hybrid adapter, by means of which it is possible to receive plug connectors from different groups. The hybrid adapter comprises an alignment sleeve for axially aligning ferrules, having a support element which defines an essentially central hole through said support element, the hole comprising a first section and a second section. The first and the second section are aligned in the longitudinal direction and are located close to one another, the inner surface of the hole tapering increasingly at a predetermined angle of less than approximately 5 degrees. The support element comprises a first inner wall which at least partially defines the first section, the first inner wall comprising a plurality of first contact points which are spaced apart from one another symmetrically over the first inner wall, the first contact points being dimensioned in order to receive a first ferrule of a first diameter which has no tapering. The support element comprises a second inner wall which at least partially defines the second section, the second inner wall comprising a plurality of second contact points which are spaced apart from one another symmetrically over the second inner wall, the second contact points being dimensioned in order to receive a second ferrule of a second diameter which is not the same as the first diameter and likewise has no tapering.
- One disadvantage of the known hybrid adapter is the fact that it is not suitable for receiving LX.5 plug connectors.
- The invention is therefore based on the technical problem of providing a universal hybrid adapter and a sleeve suitable therefore, by means of which it is also possible to connect LX.5 plug connectors to standard connectors.
- For this purpose, the sleeve is of stepped design. The transition from the first diameter to the second diameter takes place at a right-angle. The sleeve has an axially continuous slot. The right-angled transition ensures that it is possible for the ferrule having the smaller diameter to be inserted at least up to the transition, but preferably even as far as into the region of the larger diameter. Even in the case of short ferrules of LX.5 plug connectors, this ensures that the ferrules can be brought together edge to edge. Owing to the continuous slot, it is in this case possible for the sleeve to compensate for manufacturing tolerances of the sleeve itself and of the ferrules. Since the ferrules can be reliably brought together edge to edge, they may have both a UPC (Ultra Polishing Contact) ground surface and an APC (Angle Polishing Contact) ground surface. The former is a planar-parallel ground surface, and the latter is a ground surface at an angle of 8° or 9° in order to deflect reflections at the coupling point.
- In one preferred embodiment, the length of the section of the sleeve having the first smaller diameter is smaller than the length having the larger diameter. This increasingly ensures that the ferrule having the smaller diameter is inserted in the region of the sleeve having the larger diameter, with the result that better contact is made. The ratio is preferably at least 2:3, further preferably the ratio being selected to be in the region of 1:3.
- Further preferably, the sleeve is made of ceramic, bronze or plastic, ceramic being particularly preferred.
- In one further preferred embodiment, the first housing part is formed with an integrated laser protection flap, whose preferably spring-loaded flap is automatically pushed against the housing wall without coming into contact with the ferrule when a plug connector is inserted.
- In one further preferred embodiment, the first housing part is in the form of a universal adapter for small form factor connectors, reference being made as regards a preferred embodiment to DE 101 41 449 A1, express reference hereby being made to said disclosure.
- In this case, a housing half of the adapter described there is thus used as the universal interface for the small form factor connectors.
- In one further preferred embodiment, the second housing part has an opening for the purpose of receiving FC and ST plug connectors, it being possible for an FC or ST interface, which is preferably made of metal, to be inserted in said opening.
- In one further preferred embodiment, the FC or ST interface is provided with a radial groove, into which a sprung, forked metal sheet can be plugged on from the front side of a front panel. By this means, the interface can be selected to be very short, and the adapter can be detached simply and rapidly from the front side.
- In one further preferred embodiment, the second housing part has a separate sleeve receptacle for the purpose of receiving an SC plug connector, it being possible for said sleeve receptacle to be latched to the first and second housing parts.
- In one further preferred embodiment, a front frame having an integrated laser protection flap is latched onto the second housing part.
- The second housing part for the SC plug connector is preferably fixed to a front panel by means of two lateral spring clips.
- The invention will be explained in more detail below with reference to a preferred exemplary embodiment. In the figures:

Thesecond housing part 22 has anopening 29, through which theregion 12 of thesleeve 10 protrudes. On the other side of thehousing part 22 is arranged anFC interface 30 which is inserted through theopening 29 and receives theregion 12 of thesleeve 10. Thefirst housing part 21 is formed with an integratedlaser protection flap 31 which is loaded with aspring 32. Furthermore, adust protection cap 33 for thefirst housing part 21 and adust protection cap 34 for thesecond housing part 22 are illustrated inFIG. 2 . The dust protection caps 33, 34 in this case are only used if no plug connector is inserted in theadapter 20. Furthermore, two fixingscrews 35 are illustrated, by means of which theuniversal hybrid adapter 20 is screwed to a front panel (not shown), the fixing screws 35 being passed through the arched depressions on the upper and lower ends of theflanges FIG. 5 , a sprung, forkedmetal sheet 36 being used instead of the fixing screws 35 for fixing it to a front panel and being pushed into a groove 37 (seeFIG. 2 ) and fixedly clamping theuniversal hybrid adapter 20 to the front panel (not shown).
